m- Jam Specification of Letters Patent;

Patented June 8, 19 15.

Application filed August 17, 1914'. Serial no. 857,229.

To all whom it may concern Be it known that I, MYER SIGMUN, a citin ofthe United States, and a resident of cledo, in the county of Lucas andState of Ohio, have invented a certain new and use-' coolingwatersupplied to water jackets of internal combustion engines.

it has for its object to provide a radiator which may be readilyconstructed and its parts put together in such a way as to greatlyreduce the amount of solder required for closing the seams of theradiator.

It also has for its object to form laterally extending water cellsinsuch a way that the water will be deflected thereby forming laterallymoving currents of water in the'cells.

It also has for its object to provide section strips which are so madeas to cause the air to deflect and thereby produce cross or diag- 'onlybeing shown.

onal currents of air in each section as the air passes throughtheradiator when it is either blown or drawn through or when theradiator is carried by an automobile through the air.

The invention may be contained in many forms of constructions usable fordifi'erent purposes, all of which come within the pur- View of my claimshereinafter appended. To show the practicability of my invention, I haveselected one of such constructions as an example and shall describe ithereinafter. The construction selected is illustrated in theaccompanying. drawings.

Figure 1 illustrates a front view of the radiator, part of thehoney-combed portion Fig. 2 illustrates the manner in which the sectionstrips are cut. Fig. 3 illustrates one of thestripsfolded. Fig. 4illustrates two sections mounted side by side. Fig. 5 illustrates asectional view of the sections shown in Fig. 4 and 6 illustrates thepartition or reinforcing plate located between the sections.

The. radiator 1 shown in Fig. 1 is provided with the usual upper andlower com the gasolene engine in the manner well known in the art. I

4 are sections through which the water 7 passes as it is cooled fallingfrom the compartment- 2 to the compartment 3. The sections are formed ofvertically. disposed. strips which are bent so as to form watercellsthrough which the water passes vertically and air cells through whichthe air passes horizontally or transverse to the di-.

rection of movement of the water which cools the water as it descendsthrough the radiator. Each section is composed of a strip 10 which iscorrugated forming semicyhndrical. corrugations 11 and plane portions12. The semi cylindrical corrugations 11 are slotted, the slots 13 beingformed along two lines, one line being located near one edge 14 of thestrip and theother line being located centrally and lengthwise of thestrip. The plate 10 is then bent along the lines 16- of the edge' of theslots.v The edge 14 of the strip is bent over the edge 15. The adjacentparallellines 16-being located a short distance apart gives thickness tothe water cells of the radiator when plate 10 is bent to form the watercells. The edge 14 will, when theportions of the plate 10 are bent overthe edge 15, close the edges of the plane portions 12 and reinforce thelaterally extending edges of the bulging ortions located on one side ofthe section. Vhen the parts have been folded together the plate ispressed so as'to push the corrugated parts 11 together bringing the endedges of the corrugated parts in close proximity to each other. Thecurvature produced in forming the semi-cylindrical corrugations causethese portions to bulge when the edges are thus brought together. The

edges of the portions 11 are then pinched together leaving the portionsintermediate the ends bulged which give space for water circulation. Byreason of their bulged formation, the water is caused to deflect andcirculate through the laterally extending portions of the water cells.'The edges of the portions 11' are then;s0lderedto form closed seams,while the edges of the portions 12 lap over the edge 15. The lapped edge55. partments 2 and 3 which are connected to 12 and openings 17 formedat the ends of the cells are also soldered to completely close the watercells. Corrugated plates 20 are located between the sections thusformed. The plates 20 may be angularly corrugated plate 20 is providedwith holes 21 which are staggered transverse the pla'te" and extendalong the corrugations. As the air passes through the radiator thecorrugations of'the plate 20 produce diagonal currents of air within theair cells of the radiator, the air being caused to deflect transverselyas it passes through the radiator. Also, the openings allow the air tocirculate back and forth through the cells located on opposite sides ofthe plate which causes the air to circulate and be deflected back andforth bringing all parts in the metal into contact with the air, therebyrapidly cooling the water as the air passes through the radiator. Thisproduces an exceedingly eflicient radiator.

The construction selected and described, may be greatly varied in thearrangement and manufacture of its parts and in the substitution ofelements having equivalent functions and such modifications may be usedfor many varied purposes and still contain the invention.

Having thus described my invention, what semi-cylindrically corrugated.Each I claim as new and desire to secure by Letters Patent, is,-

1. In a radiator, a strip having. spaced corrugations and slottedcentrally across the corrugations and near one edge of the strip andfolded centrally and having one edge turned over the opposite edge alongthe slots, forming vertical and transverse water chambers. I

2. In a radiator, a strip having spaced corrugations and slottedcentrally across the corrugations and near one edge of the strip andfolded centrally and having one edge turned over the opposite edge alongthe slots, forming vertical and transverse water chambers, a corrugatedstrip located between the first-named strips and spaced by thecorrugations of the first-named strip and having openings arranged alongthe corrugations of the lastnamed strip and staggered in theirarrangement across the corrugations of the last-named strip.

In testimony whereof, I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.

MYER SIGMUN.
